Marque - which operating system and poser and pro pack version are you using? Yours is the first time we've heard of a PC problem with any clothes in this set. I am re-reviewing the bikini bottom file but nothing has jumped out at me yet. Please let me know which clothes are giving you problems and which aren't so that we can try and find a common thread. Given the pattern or working and not working this is shaping up as some kind of weird file format twitchiness, possibly pro pack related.
